摘要
分析了湖南省的气候特点、水资源状况以及水源热泵系统对水源系统的要求.以湖南省湘潭市某人工湖水源热泵空调工程为例,对人工湖水源热泵系统在湖南地区的应用进行了实例分析.除了分析地表水温与气温之间的定性关系之外,还将水源热泵系统的名义工况能效比、性能系数、初投资、年运行费用与风冷热泵系统进行了比较.结果表明,水源热泵系统的年运行费用比风冷热泵系统少82.6万元,可节约32%以上.多余的初投资在2～3年内可以通过运行费用的节省而得到回收.
The climate and water source characteristics of Hunan province were analyzed. The requirements to water source of ground surface water heat pumps(SWHPs) (or manmade lake water heat pumps) were pointed out. On the basis of a SWHP system in Xiangtan, Hunan province, the application of SWHPs in Hunan province was studied. The relationship between surface water temperature and outdoor air temperature were analyzed qualitatively. The nominal EER, COP, initial investments and running costs of SWHP systems were compared with air source heat pump (ASHP) systems. It was concluded that SWHP systems in Hunan province can save over 32% of costs compared with ASHP systems and their more initial investment can be reclaimed within 2~3 years.
